IMPROVEMENT IN LANTERNS.

Specification forming part of Letters Patent No. 58,392, dated October2, 1866.

To all whom it may concern:

Be it known that I, A. M. DUBURN, of Ohicago, in the county of Cook andState of lllinois, have invented a new and Improved Lantern; and I dohereby declare that the followin g is a full, clear, and exactdescription thereof, which will ,enable others skilled in the art tomake and use the same, reference being had to the accompanying drawings,forming a part of this specification, in which- Figure l is a side viewof my invention, partly in section; Figs. 2 and 3, detached per spectiveviews of the wick-adjusting mechanism; Fig. 4, a plan or top view of thesame;

Fig. 5, a section of Fig. 4, taken in the line as a0.

Similar letters of reference indicate like parts.

This invention consists in a novel manner of constructing the lantern,whereby all parts of thesame are rendered accessible for repairs andcleansing purposes, the wick rendered capable of being adjusted higheror lower without detaching the lamp from the lantern, and the lampsupplied with a burner which does not require a draft-chimney.

A represents a lamp, which is attached to a flange, B, the latterforming the base of the lantern. The upper surface of this base has anupright annular rim, a, secured to it, with a bead, b, at its upperedge, under which flanges c c on the lower edge of the bottom band, 0,;of the body of the lantern project, as shown in Fig. 1, the lamp A andband (J being by this arrangement connected together, while they areallowed to turn freely.

The lamp is fitted in and withdrawn from the lantern by shoving theflanges 0 through recesses c in the head I), one of the said re cessesbeing shown in Fig. 1. v

D represents the wire guards of the lantern,

which may be constructed and arranged in the usual way, the lower endsof the uprights being secured to the band C.

The upper horizontal guard, d, has the cap E of the lantern. secured toit by a hinge, c, and said cap is provided with a catch, f, by which thecap is secured down on the guard d when the lantern is in use.

The cap E may be constructed in the usual manner and provided with ahandle, F.

G represents the glass globe of the lantern,

the lower edge of which has a metal band, 9, upon it. This globe restsupon spring-supports h h, which are attached to the inner sides of theband C, the globe being allowed to fit within the guards, so that it maybe withdrawn therefrom down through the band (l when the lamp isremoved, the lower part of the cap E, when secured down on. the guard01, fitting over the top of the globe G and retaining it in position.The globe may be withdrawn at any time by simply pulling out ward thespring-supports h h, the lamp being previously withdrawn.

H represents the burner of the lamp, which has a flat wick-tube, 2',provided with two plates, jj, at its upper end, which project outhorizontally from two opposite sides of the wick-tube, and are then bentover toward the wick, as shown clearly in Fig. l, and have their edgescurved and their ends bent down ward, as shown in Figs. 4 and 5.

By this arrangement an air chamber is formed around the upper end ofthe'wick and the base of the frame is spread, so that it will be thinand have a large area exposed to the air above the edges of the platesjj.

The wick is raised and lowered by means of the usual serrated wheelsfitted on a rod, 70,

which passes horizontally into the base of the burner. The outer end ofthe rod 70 has a square, Z, upon it, as shown in Fig. 3, and through theband C a short horizontal rod, m, passes, with a socket, n, at its innerend to receive the squarel of rod 70. The squarel may be fitted in thesocket a by turning the lamp A or the band C, and, the rods k and atbeing thus connected, the wick may be raised and lowered .by turning therod in, and, consequently, without removing the lamp from the lantern.

When it is necessary to remove the lamp from the lantern, the lamp orthe body of the lantern is turned so that the square l will be out ofthe socket a, and the rods 1: .m will consequently be detached, the rodm remaining in band 0 when the lamp is withdrawn.

The lamp may be lighted, without? removing it from the lantern, byraising the cap E.
